I don’t think she wants attention and I don’t think she wants you. The maybe was almost definitely a no in the nicest way she could think of at the moment and the snaps are most definitely how she communicates with her friends. Your other friends are hyping you up but seeing as how none of you seem to be particularly close to the girl in question, I would take that with a grain of salt.
Like she went home and still sent pics of herself and I asked if she wanted drinks and she just says huh? I sent a longer snap offering to get drinks with her and it sat unopened for 40 mins so I deleted it and went to bed, an hour later she sent a question mark. I’m guessing she just wants attention
